Reporting suspected fraud in Thailand

Evidence preparation and complaint deadlines

If you suspect fraud in Thailand, preserve payment and communication records promptly, explain whether you want the authorities to investigate and pursue criminal responsibility, and ask Thai counsel to check the offence, jurisdiction and complaint deadline. Certain compoundable offences have a three-month complaint period. A promise to repay is a reason to assess the deadline now, rather than leave it until negotiations end.

This guide is for individuals and businesses dealing with suspected transaction, investment or other property fraud in Thailand. The document checklist is a preparation aid. The required documents and available legal routes depend on the facts. If a transfer scam is still unfolding, also contact your bank and verified official Thai police channels promptly. Do not wait until every document has been organised.

Identify what was said and when

Late payment, an unsuccessful investment or an unfinished transaction calls for an examination of the surrounding facts. Section 341 of the Thai Penal Code addresses dishonest deception through a false statement or concealment of a fact that should be disclosed, which leads to obtaining property or certain dealings with a document of right. The fact that money has not been recovered does not, by itself, establish all of these elements.^[S1]

Start with the representations made before payment. What was later found to be untrue? Why did you rely on it? Which payment followed from that representation? Match contracts, messages, promotional material and payment accounts. Keep first-hand facts separate from information supplied by others and matters that remain unverified. Describe suspicions as suspicions.

Where the available evidence mainly concerns performance or payment, prepare the materials relevant to a civil claim as well. Our existing unpaid-invoice evidence checklist explains how to organise contracts, delivery and the balance claimed. Any possible criminal responsibility requires its own factual and legal assessment.

Check what the complaint actually records

A victim's criminal complaint is referred to in Thai as “ร้องทุกข์”. Section 2(7) of the Criminal Procedure Code describes an allegation to the competent authorities that an offence has caused injury, made with the intention that the offender be punished. A complaint does not invariably depend on already knowing the offender's full identity.^[S2]

If you want criminal responsibility pursued, explain this clearly and check that the record accurately reflects your intention. A visit, telephone enquiry or record made only to document an event should not be assumed to satisfy the requirements of a valid complaint merely because it took place. The content, complainant's capacity, receiving authority and method of submission can matter.

Where possible, obtain or request a copy of the record. Note the date, receiving unit, contact person and reference number, and ask what further material is needed. Have counsel examine the actual documents rather than assess the procedure or deadline solely on a statement that the matter has already been reported.

When the three-month period needs attention

Under section 96 of the Penal Code, subject to the general limitation rules in section 95, a victim of a compoundable offence must complain within three months of knowing both the offence and the offender. When those two elements of knowledge arose depends on the evidence.^[S1]

Ordinary fraud and fraud against the public can involve different rules. Section 348 makes offences in the fraud chapter compoundable except for section 343. It is therefore unsafe to apply one three-month deadline to every fraud allegation, or to assume that all remedies have expired merely because the payment was made some time ago.^[S1]

Record the payment date, when possible deception was discovered, when the relevant offender became known, and every previous report or submission. Preserve the documents supporting each date. Do not treat a repayment promise, ongoing negotiation or a payment demand as proof that a valid criminal complaint has been made or that a deadline has been protected. If time may be short, have Thai counsel assess the position promptly instead of waiting for the next response.

Build a factual evidence file

Section 123 of the Criminal Procedure Code requires the complaint to contain the complainant's name and address, the nature and circumstances of the offence, the injury suffered, and the offender's name or description so far as it can be given. A complaint may be written or oral, with statutory requirements concerning dates, signatures and recording.^[S2]

The following is a practical preparation list, not an official attachment checklist for every case:

• Prepare a short chronology covering contact, representations, agreement, payments, discovery, follow-up and reporting. Give each supporting item a reference number.
• Gather identity and authority documents. Where a company suffered the loss, establish which entity is the victim and who is entitled to act for it. Confirm the required authorisation documents with counsel and the receiving authority.
• Preserve identity leads, including known names, company details, account identifiers, payment accounts, contact details, websites and meeting locations. Distinguish verified identities from names someone merely used.
• Match the alleged deception to the payments. Retain pre-payment statements, contracts and attachments, full communications, bank records and transfer confirmations. Note the date, currency, amount, payer and recipient of each transfer.
• Record loss and subsequent steps. Separate amounts paid, refunded and still outstanding. Retain relevant expense records, previous complaints and acknowledgements of additional evidence. The recoverable heads of loss require a separate assessment.

If material is missing, record what it is, who holds it and when it may be available. Do not recreate evidence or alter originals. Translation, certification, inspection of originals and formatting requirements depend on the case and the receiving authority.

Preserve Chinese messages and electronic records

Electronic form alone is not a reason to exclude evidence, but authenticity, integrity and the connection to the relevant people still matter. ETDA's explanation of section 11 of the Electronic Transactions Act distinguishes admissibility from the weight a court gives electronic material.^[S3]

Keep the original devices, accounts and files. Where feasible, export complete conversations or emails and retain separate readable copies. Screenshots should include account identifiers, dates and surrounding context rather than isolated favourable sentences. Record who extracted each item, when, from which device or account, and where it was stored.

Chinese originals and Thai translations should correspond item by item. A translation assists understanding; retain the original for checking. Do not give passwords, one-time codes or remote access to unknown people offering recovery services, or access someone else's account without authority in an attempt to gather evidence.

Arrange language assistance and follow up on specific matters

Section 13 of the Criminal Procedure Code provides for Thai to be used in criminal proceedings and for the relevant inquiry official, public prosecutor or court to arrange an interpreter where a victim or another specified participant cannot speak or understand Thai and has no interpreter.^[S2] Explain your language needs early. Before signing a statement, have important content interpreted and identify any factual corrections. Do not sign a record you have not understood.

Follow-up is more useful when it addresses specific questions: which unit and person is handling the matter, what information is outstanding, which evidence has been submitted, and whether attendance or further documents are required. Keep a dated contact log and avoid inconsistent submissions from different people. Counsel can review the documents and procedural record before agreeing a scope of assistance. The competent authorities determine the progress and outcome in accordance with the law.

Plan recovery alongside the criminal process

Assess the return of property, compensation and any civil proceedings separately. Identify the losses that can be claimed, the appropriate parties, supporting evidence, applicable deadlines and any assets potentially available for lawful enforcement. A complaint acknowledgement, investigation or criminal judgment should not be treated as a guarantee that money will be recovered.

Before signing a settlement, payment acknowledgement or withdrawal, obtain advice on its effect on both criminal and civil rights. Section 39(2) of the Criminal Procedure Code provides that a lawful withdrawal of a complaint or prosecution, or a lawful compromise, extinguishes the right to bring a criminal prosecution for a compoundable offence. The consequences for different offences and other claims must be checked separately.^[S2] An arrangement requiring withdrawal before payment deserves particular care.
